running the system as is @16K TS long term probably serveral months for this one to get done I plan on continuing to watch it for at least 100 Myr, if not more. current estimates place progress @ 2 Myr per true day.

I think that in the case of the 5 Gas giant sim if they had had inclinations of at least +/-1 deg or more it would have remained stable.

I wouldn't use that simulation if you're planning on dedicating a lot of your computer's time. It was created under the old version as a quick solar system simulation. The later simulations have a slightly more accurate solar mass. Also, that sim starts out at 65K time step, so you've already lost some accuracy compared to a 16K run. Also, the planets with moons completely ignore the moons, rather than include them in the planet mass as a system mass.
